From what I know, if it was a problem with my dfa reservation assert, it would have ICEd in riscv.cc and not riscv-v.cc. For now I reverted the changes since I don't want to leave things possibly broken overnight and not knowing which patch is the root cause. I kicked off another set of test runs using our full gcc postcommit testing configurations and should have those results in tomorrow. Hopefully it was just a missed config target I didn't test and wasn't tested on the precommit ci.

Hi Juzhe,

I didn't see any ICEs when I tested locally (tested on https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=8123f3ca3fd891034a8366518e756f161c4ff40d). Can you tell me what config you're using?
